Does it work to splash face with hot water and wash it with cold water??

I am thinking about trying this. i have heard it works. has anyone had any experience with this?Does it work to splash face with hot water and wash it with cold water??
My mother is 63 years old and has the skin of a woman in her thirties. When she washes her face she wets a soft face towel with hot water and gently wipes with the towel slightly damp. She does this a couple of times then she wets the towel with cold water and pats her face with it. All I can say is even though she doesn't splash her face with hot water, she does get a good effect from it. She doesn't scrub her face because that is damaging to skin. She has been doing this over half of her life. The hot water opens pores and lets your face get a deep clean and the cold water closes your pores back up.Does it work to splash face with hot water and wash it with cold water??
yeah it works...the hot water is meant to open your pores and the cold water is meant to close them so they appear smaller
yes it works it helps me try it
